Thx a lot !! that worked !
Actually, I had to do this (just in case somebody would have the same bad
idea I had and would read the posts in this list ;)) :
1. copy gzip from /rescue to /usr/bin (maybe not the good location, but I
could use it, so..)
2. mkdir /usr/tmp && cd /usr/tmp
3. /rescue/cat /cdrom/base/base.?? > usr.bak
4. /rescue/tar --unlink -xpzf usr.bak
And then, I just get what I needed, and had only to copy the missing file.
Being able to RTFM again is so great !
Thanks a lot for your tip.
